G234 - Tool Center Point Control (TCPC) (Group 08)
28
F4.1:
Location of Workpiece Defined by G54
In Figure
, the B and C Axes have been rotated 15 degrees each. To create the same
edge, the machine needs to make an interpolated move with the X, Y, and Z Axes. Without
TCPC, you would need to repost the CAM program for the machine to correctly create this
edge.
F4.2:
G234 (TCPC) Off and the B and C Axes Rotated
TCPC is invoked in Figure
. The Haas CNC control knows the centers of rotation for
the rotary table (MRZP), and the location of the workpiece (active work offset G54). This
data is used to produce the desired machine motion from the original CAM-generated
program. The machine follows an interpolated X-Y-Z path to create this edge, even though
the program simply commands a single-axis move along the Y Axis.
